WAGON-BOLSTER AND DETACHABLE STARE.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed June 5, 1919. Serial No. 301,912.

To all whom t may Concern.'

Be it known that 1, HERMAN F. MILLER, a citizen of the United States, residing at lNittenberg, in the county of Shawano and State of l/Visconsin, have invented certain new and useful Improvements in l/Vagon- Bolsters and Detachable Stakes, of which the :following is a specilication.

This invention relates to improvements in wagon holsters and stakes.

The object of the invention is to provide a combined wagon bolster and stake which are constructed to coperate so that the stake may be readily applied and removed as desired, and when applied, will be rigidly held against accidental displacement.

Another object is to provide an apparatus of this character which is cheap to manufacture and strong and efficient in o eration.

With the foregoing and other o jects in view, which will appear as the description proceeds, theinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment oi' the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 is a side elevation of a wagon bolster constructed in accordance with this invention with a stake shown at the left ir, operative locked position and one at the right in position with the locking means shown released and depending from the bolster.

Fig. 2 is a bottom plan view of one end of the bolster,

Fig. 3 is an end view thereof, showing a front elevation oit' the stake,

Fig. 4 is a perspective view of the eXtension,

Fig. 5 is a detail perspective view of the locking cam, and

Fig. 6 is a transverse section taken on the line 6-6 of Fig. 1.

In the embodiment illustrated, a bolster 1 of ordinary construction is shown, having at its opposed ends U-shaped strap irons 2, the legs oit' which are secured to the opposite sides of the bolster and which straddle the bolster ends as is shown clearly in Figs. 1 and 2. Extending vertically through the bolster ends are stake receiving sockets 2 which are inclined downwardly and inwardly at their-outer ends as is shown at 2". Links 3 are pivotally connected at one end to opposed faces of the bolster ends and have their free ends a oiiset inwardly to space them a proper distance to receive a pivotally mounted Cain 5. lThis cam 5 has an extension 6 forming a handle or actuating member which is equipped on one face with an outwardly bowed plate spring 7 for a purpose presently to be described.

Thebolster 1 is designed to support at its opposite ends removable stakes as l0 which are exactly alike in construction and hence one only will be described in detail. Each stake 10 has its lower end inclined on its outer face as shown at 1l with a block 12 extending laterally at the top of said int clined portion and which is here shown seq cured to the stake by bolts 13', although obviously it may form an integral part thereof if found desirable. rThe lower end of the stake is designed to fit in the pocket or socket .2 and the lower end oi block 12 abuts the upper edge or face of the bolster 1 pe yond the pocket 2 therein as is shown clearly in Fig. 1.

The upper end of block 12 has a concave seat 14 designed to receive the locking cam 5 when the parts are in operative position as shown at the left of Fig. 1. This stake 10 has its opposite side faces grooved as shown at 15 to provide longitudinal guides for a keeper 16 which is slidable on the stake and adapted to slip over the arm or handle 6 of the cam 5 to hold the cam in locked engage ment with the stake, the spring 7 operating to retain the sleeve in proper position.

The stakes 10 may if desired, have eXtensions 17 to increase their height, said eXtension being shown detached in Fig. 4, and which is secured to the stake 10 by means of a J-shaped bolt 18 which passes through the upper end of the stake extension 17 and engages a strap 20 on the stake 10 so that the extension 17 is securely secured to stake 10 when the parts are assembled. The eXtension 17 has a recess 21 in one edge to form a seat for strap 3, the strap 19 being hooked around the stake.

In the use of this invention, when it is desired to remove the stakes 10 from the bolster 1, the cam lever 6 is swung downwardly, the keeper 16 having iirst been slipped up out of engagement therewith, and when so released,

the links 3 will drop down into the position I shown at the right of Fig. l, when the stake l may be lifted out of its pocket.

To insert a stake, the lower inclined end 11 thereof is inserted in pocket 2', the links 3 being thence swung up into the position shown at the left of Fig. l, which positions cam 5 to be seated in the seat 14. This cam is then swung upwardly with its lever or handle 6 flat against the outer face of the stake, and the keeper 16 is slipped down thereover, and yieldably heldin adjusted position by the spring 7.

From the above description it will be obvious that the stakes may be quickly applied or removed when desired, and when applied will be securely locked against all possibility of accidental detachment.

IF rom the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and while I have described the principle of operation of the invention together with the Adevice which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

l. The combination with a wagon bolster having a stake pocket, a stake to fit said pocket having a lateral projection to rest'on the upper face of said bolster, a cam lever carried by the bolster to engage said projection to lock the stake to the bolster, and a keeper slidable on said stake and adapted to engage said lever to hold it in operative position.

2. The combination with a wagon bolster having a stake pocket, a stake to fit said vpocket having a lateral projection adapted to rest on the upper face of said bolster, and provided with a concave seat, links pivoted to the end of the bolster and straddling said end, a .cam levercarried by said links and adapted to engage the seat of the stake, and means for holding said lever in operative position.

3. rIhe combination with a wagon bolster having `a stake pocket, a stake to t said pocket having a lateral projection adapted to rest on the upper fac'e of said bolster and provided with a concave seat, links pivoted to the end of the bolster and straddling said end, a cam lever carried by said links and adapted to engage the seat of the stake, and a keeper slidable on said stake and adapted to engage said cam lever to hold it in operative position.

a. A wagon stake having a detachable extension with a strap hook from one edge near one end with a recess in said end above said hook and a hook projecting laterally fromone face of said extension, said stake having means for coperating with said hooks and recess to hold the extension engaged with the stake.

In testimony whereof I afliX my signature in presence of two witnesses.
